The business is still around - it was taken over (after the death of the brothers) by Audio Dynamics - check this link.

My only connection with them is that I had a Blue Point Special - on which I had snapped the cantilever - rebuilt by them, and I'm very happy with it.

Decibel Hi-Fi, the agent in the link, also seems to have really good prices on other stuff. I bought a digital stylus pressure gauge from them and had it shipped back with the cartridge - it ended up costing me about half of what I would have paid in Canada, even with shipping.
